Recent research has focused on polymethane semisilane powders prepared through morphological control growth and their composite materials with hydrosolytic latex for the manufacture of ultra-hydrophobic coatings.
incompatible between ultra-hydrophobic particles and water-based latex prevents them from mixing directly to prepare mixtures for the manufacture of ultra-hydrophobic coatings.
polymethyl double semisilane (PMSQ) prepared by the pre-methyl tritanyl silane system can change from hydrophobic to hydrophobic with increased
. This feature makes PMSQ suitable for mixing with water-based latex to create highly hydrophobic coatings.
new work has proposed a method of morphological control of PMSQ to produce highly porous PMSQ particles with micro/nano roughness on the surface. The PMSQ gel is first prepared in a water-based medium and then broken into small pieces by a high-speed homogeneity machine, and additional acid-catalyzed methyl methylene silane hydrolysis products are added to the dispersion of the broken particles.
a dry, ultra-hydrophobic coating
pre-empts alkali-catalyzed PMSQ regeneration on a pre-fabricated gel skeleton, resulting in a high-porous PMSQ powder suitable for hydro-latex complex. The composite materials of PMSQ wet powder and styrene-acrylic hydro-latex are super-hydrophobic after drying under ambient conditions, and their water contact angle reaches 153.1 degrees and sliding angles as low as 28.7 degrees.
the study has been published in the Journal of Coating Technology and Research, September 2019, volume 16, No. 5.
